Put, two grades of wash mills and tail gas funnel, described one-level wash mill includes Venturi tube, the fluorine silicon being sequentially connected with along pipeline
Acid circulating slot and channel washer, described Venturi tube is all connected with described hexafluosilicic acid circulating slot with the bottom of channel washer, institute
Stating extraction tank air inlet superposed with Venturi tube to be connected, described two grades of wash mills include tail gas washing tower and foam removal tower,
Described channel washer gas outlet is connected with described tail gas washing tower air inlet, described tail gas washing tower gas outlet and described foam removal
Tower air inlet connects, and described foam removal tower is connected with described tail gas funnel, and is provided with water inlet below described tail gas washing tower, described
Foam removal tower is arranged over shower.
Further, between described foam removal tower and tail gas funnel, it is provided with exhaust fan.
Further, in order to ensure the abundance that supplies water, described tail gas washing tower water inlet and shower are all connected with industry water pipe
And running water pipe.
Compared with prior art, the beneficial effects of the utility model are:
In this utility model, phosphoric acid tail gas system is under the effect of exhaust fan, the trachea at extraction tank exhaust gas flow direction top,
Enter in Venturi tube and channel washer, wash as one-level.Two grades of washings are carried out subsequently into tail gas washing tower, foam removal tower.
It is discharged to chimney through exhaust fan after.In Venturi tube, detersive efficiency is high, effectively reduces delivery temperature.Add foam removal tower, it is ensured that
The cleaning of exhaust emissions.In order to prevent the silica gel carried secretly in tail gas in impeller and chimney bonding, in foam removal tower use spray
Pipe is sprayed water, and makes temperature reduce, and solid phase separates out sedimentation further.
